Is there any way that you might have 2 postgresql processes running? Say
one cygwin process and one win32?
Just curious. That might explain why psql is not letting you connect,
because it is trying to connect to a different one.
Anyway, for pgAdmin, there is a button that looks like a pencil which
lets you execute arbitrary SQL requests. Or it should be under
"Tools/Query Tool" if you want it from the menu.
